THEODOB SCHILD, OI GBENCHEN, SWITZERLAND POCKET LIGHTING DEVICE Application fled June 18, 1987, Serial 170.

The present invention relates to a new and improved device for lighting pipes, cigars, etc. and more especially to a device adapted to be carried in the pocket and comprising 5 a container containing material soaked in gasoline or equivalent spirit and feeding a wick, a piece of pyrophorous metal arranged in proximity to said wick and a rotary scraper with abrasive surface frictionall engaging said piece of pyrophorous meta in such a manner that by turning said scraper sparks are produced serving to. ignite the gasoline ascending by said wick.

The main object of the invention is to provide a. device of the said class which allows an easy and rapid cleaning and inspection.

Another object of the invention is to provide an improved device which shall be simple, strong and durable in Eonstruction and efficient in use.

Other objects ofthe invention relate to the provision of minor parts and to details of construction all of which will be more clearly set forth in the following specification.

I attain these objects by placing the pyrophorous metal piece together with a spring pressing the same on to the abrasive surface of the rotary scraper disc into acasing rotatably arranged on the axis of rotation of said scraper disk in such a manner that the casing may be made easily accessible by swinging it out of the container in which it is normally placed.

In the accompanying drawings forming part of the specification a preferred mode of construction is shown by way of an example.

Fig. 1 shows the top portion of a pocket lighting device in sectional elevation,

Fig. 2 is a top view, the lid of the device being removed, 7

Fig. 3 is a cross-section on line IIIIII of the drawing 1- denotes a container with 'a compartment 5 in which a material soaked with gasoline, petrol or equivalent spirit is stored. The container 1 is moreover provided with a lid 2 hingedly connected to said container 1 at 3. In the chamber formed by the top wall 4 and by the lid 2 a tubular casing 9 is rotatably arranged. A cylindrical 199,712, and in Switzerland April 6, 1827.

stud 13 projects through a cross bore of said casing 9. The stud 13 forms plrt of a piece 12 rigidly connected to the we 4. A screw '11 wlth a large head screwed into said stud 13 secures the casing 9 against axial dis lacement. On the stud 13 a round disk 6 of ardened steel or the like is rotatably mounted. The surface of the disk 6 is roughened to form a scraper. A piece 7 of pyrophorous metal placed in said casing 9 is pressed against the roughened surface of the disk 6 by means of a coiled spring 8 abutting against a set screw 10 screwed into the free end of casing 9. The casing 9 rests on a support 15 fastened to the wall 4, the support 15 is provided with a shallow groove engaged by the casing 9, the latter being secured thereby against accidental displacement. In close proximity to the disk 6 and piece 7 a wick 14 is arranged in the well known manher. By turning the disk 6 sharply a gerb of s arks is produced which are thrown on to t e wick 14 igniting the vapour ascending therefrom.

o inspect, to clean and to adjust the igniting device proper and to refill the casing 9 the latter is turned into the position shown in dotted lines (Fig. 2

The support 15 may e replaced by a snap fastener or any other device retaining the casing 9 in its working position.

It will be obvious that changes of details 'may be made within the true scope of the invention which is set forth in the claims.

What I claim and wish to secure by U. S. Letters Patent is 1. A pocket lighting device, comprising a fiat container substantially rectangular in ,cross section and having a horizontal supporting wall adjacent one of its ends, a vertical stud fixed in said wall, a'tubular casing rotatable in a horizontal plane about said stud parallel to said supporting wall, a friction wheel also rotatable about said stud and partly enclosed in said tubular casing, and a spring pressed pyrophoric element in said casing and adapted to adjustably engage said friction wheel.

2. A pocket lighting device, comprising the combination with the elements claimed in claim 1, of a. grooved block mounted on said sup' orting wall at a point remote from said stu and adapted to receive the end of the tubular casing remote from said stud.

In witness whereof I afiix my signature.

THEODOR scum).
